vcitizen of the UnitedStates, residing at Ottumwa, in the county of WVapello and State of Iowa, have invented certain new and useful Improvements in ater-Pressure Systerns, of which the following is a specification.

This invention relates to certain new and useful improvements in water pressure sys .tems, and especially to that type adapted for country homes, and it consists in an imv proved combined air and water tank arranged in the water of the well, together with w an air pressure supply and a water load both connected to the tank in the well.

The invention further, resides in the features of construction, the arrangements and combinations of parts hereinafterdescribed in detail and succinctly defined in the ap pended claims, reference being had to the accompanying drawing wherein like nu merals of reference designate like parts and v Figure 1 is a diagrammatic view illustrating the improved water pressure system in its practical embodiment; and

Fig. 2 is a vertical section of the combined air and water tank. 7

Referring more in detail to the drawing, the numeral 1 designates an air pump, of any desired or suitable type, having communication with a'pressure storage tank 2 for supplying compressed air thereto for the purpose hereinafter referred to.

The combined air and water tank 3 is arranged in the water at the lower portion of the well 4 and comprises an upper air compartment 5 which is connected to the air 7 7 compartment 5, after the valve 7 ls'opened,

pressure storage tank 2 by a pipe 6, the latter having a shut-01f cock or valve 7 therein for controlling the supply of air to said air compartment 5. Said tank 3 has a water compartment 8 underlying the air compartment 5 and preferably of much larger capacity than said compartment, the two compartments being communicatively connected through a port 9 adapted to be closed by a valve 10, said valve being of any suitable type although a ball valve is herev shown. A spring 11 urges the valve to JAMES s.. RAGAINS, or. 'o'rrUMwA, IOWA.

I pecification of laettersiPate nti Pa iliollte diApi; 16, 1918.

Application filed March 12, 1917. Serial No. 154,089. 7 I v its seat, a pin 12 serving to hold the spring '7 in position,

The bottom wall of compartment 8 is.

provided with an inlet opening or port 13 adapted to be closed by a ball valve 14,

or other type of valve, a pin 15 extending across 151161111161 end of the valve cage 16 to retain said valve against displacement.

A water conducting pipe 17 is connected with the water compartment at its lower end, said pipe leading to the house, or other suitable points of delivery, as through fau cet- 18. The valves 10 and l l'both open inwardly within the water compartment 8 so that air may pass through port 9 and water through inlet 13 into the water compartment 8, but said valve 10 will close against water entering the air compartment 5 and said valve 14 will close to prevent the egression of water throughsaid port 13. Thus if air is admitted into compartment 5 under pressure, the valve 10 will open and the valve 14 close to permit the air pressure forcing the water in compartment 8 out through pipe 17.

In practical operation the valve 7'is closed permitting fresh water to flow into the water compartment 8, the valve 10 closing to prevent passage of the liquid into the air compartment 5. It is therefore obvious that no matter how deep the tank 3 may be disposed, theair compartment will always remain free of water. It will further be noted that this air compartment will serve as a float to buoy up the tank and thereby relieve the piping 6 and17 fromthe weight of said tank. r I I As'soon as faucet 18 is opened, the air in will unseat valve 10, close valve 14:, and

force the water in said compartment 8 out of the latter through the draw-off pipe '17. Consequently, fresh and cold water direct from the well is always obtainable, and since the present system embodies but few parts the same maybe cheaply manufacsaid tank comprising a floating air Cllzlllb her and a communicating Water chamber, the latter having valves permitting the ingress of Water and air and closing against the egress of the Water, means for supplying air under pressure to the air compartment, and a draw-off pipe connected to the Water compartment. 7

2. In a Water pressure system a Water compartment adapted to be immersed in a body of Water and having a Water inlet Copies of this patent may be obtained for controlled by an inwardly opening Valve, an air compartment arranged to exert a buoying influence on the Water compartment and communicating with the latter through a passage, a valve closing the passage against the flowing of Water from the first compartment to the air compartment a drawofi pipe leading from the former, and air pressure means for the a1r compartment.

In testimony whereof I athx my slgnature.
